In a large bowl, mix the flour, cinnamon, baking soda, and salt. In a separate bowl, mix the oil, eggs, and sugar. Stir the oil mixture into the flour mixture just until moistened. Fold in the peaches and ginger. Spoon into the prepared muffin tins. Bake for 20-25 minutes until a toothpick inserted into the center of a muffin comes out clean. Cool the muffins in the pans for a few minutes before placing them on wire racks to cool completely. Makes 24 muffins.
